3 Notes on documentation These assembly instructions are aimed at tradespersons who are familiar with assembly and installation of the heater trained specialists who are familiar with operation of the heater. Other applicable documents Assembly and operating instructions exist as paper documents for the unit types described here and are enclosed with the equipment. We cannot accept any liability for damage associated with failure to observe these instructions. Where applicable, the instructions for any accessories used also apply. Notes on documentation 2 Safety notes When performing the electrical installation, it is important to observe all valid national and regional regulations as well as the provisions of the responsible electrical supply company. Electrical installation must only be carried out by a qualified electrician who is responsible for compliance with the existing standards and regulations. Use only original spare parts! The heater must not be touched while switched on. Risk of burns from hot surfaces! The heater must be allowed to cool for approx. 5 minutes after switching off. EN.2 CE certification The declaration of conformity is supplied with the unit as a separate document. Caution! Risk of burns from hot surfaces!.3 Retention of documents These instructions and all associated documents constitute an integral part of the product. They must be given to the plant operator. The operator is responsible for storage of the documents so they are readily available when needed..4 Symbols used The bullet point indicates an action to be performed. Danger! Immediate danger to life and limb! Caution! Potential threat to the product and its environment. Note: Useful information and special features. Rittal enclosure heater assembly instructions 3

However, the functions are identical in principle. 2 Without fan 3 4 With fan Fig. : Device description ey Aluminium section (without fan) or heater housing (with fan) 2 Protective cover for electrical connection 3 Base plate 4 Fixing points 3. Functional description Heaters are used to prevent the formation of condensation inside the enclosure and maintain a constant minimum operating temperature (e.g. when the system is switched off overnight). Rittal heaters achieve thermal outputs of 8 to 870 watts. 3.. How it works The heaters are comprised of the following main components: Heaters without fan Aluminium section PTC heater element Heaters with fan PTC heat register Fan Control A separate thermostat (30.000) or a digital thermostat (34.200) must be used to control the enclosure temperature. The humidity of the air in the enclosure can be controlled by incorporating a hygrostat (38.000). 3.2 Proper use Rittal heaters were developed and designed in accordance with the state of the art and the recognised rules governing technical safety. Nevertheless, if used improperly, they may pose a threat to life and limb or cause damage to property. The heater is designed to heat closed enclosures that are only accessible by trained specialists. The admissible temperature range is -33 C to +65 C. The manufacturer will not be liable for any damages caused as a result of improper use, or for incorrect assembly, installation or use. All risk is borne solely by the user. 3.3 Scope of supply The heater is supplied in one packaging unit. de Qty Desig ati Tab. : Scope of supply Base plate Aluminium section Cover cap Assembly instructions Assembly parts (see fig. 2) 4 Rittal enclosure heater assembly instructions Heater (pre-assembled) Assembly instructions Assembly parts (see fig. 2)

5 4 Mounting The heater is fitted vertically, i.e. with the connection terminal or fan facing downwards. To permit the required convection, a minimum clearance to the adjacent components must be observed. A safety clearance of at least 300 mm must be left at the air outlet in the case of heaters with fans, and 00 mm for heaters without fans. (For both heaters a thermal safety clearance to the sides of 60 mm and 00 mm at the bottom is required). If these clearances are observed, the ambient temperature at the air inlet does not rise above 65 C. There are two different methods of assembling the heater:. Snap-type fastening onto a 35 mm support rail DIN EN (fig. 2). 2. Screw fastening onto the mounting plate (fig. 3). It should be ensured that the heater and connection cables are mounted firmly and securely. Electric cables must not touch the body of the heater fan and must not be routed directly past the hot air outlet. The heater must not be mounted in the vicinity of flammable materials. 5 Electrical connection 5 Electrical connection The heater must be connected, via the quickconnect terminals, to a power supply of the voltage stated on the rating plate. The heater must be connected to the mains via an all-pole isolating device in accordance with the overvoltage category III to EN Only copper wires are to be used for the electrical connection. Due to the special characteristics of the PTC heater element, a current of up to 4.4 A may be reached for a short time when the heater is switched on. Slow-blowing fuse-links (gg) or circuitbreakers with a corresponding delayed-trip characteristic can be used as pre-fuses. The required pre-fuse rating is specified on the rating pate. Overvoltage protection is to be provided where pulse loads exceeding,000 V are possible. The double connection terminal permits the cascading of several heaters and thus simplifies wiring. In such cases, it may be necessary to adapt the prefuse rating to accommodate the total start-up current. The maximum switching capacity of the devices must nevertheless be observed. EN Note: In justified, exceptional cases, heaters with fan ( W) may be installed rotated through 80. Please note that, in case of mounting on a 35 mm support rail, the mounting clips must also be rotated through 80. Rittal enclosure heater assembly instructions 5

6 6 Storage and disposal EN 6 Storage and disposal Caution! Risk of damage! The heater must not be stored at temperatures above +65 C or below -33 C. Disposal can be performed at the Rittal plant. Please contact us for advice. 7 Warranty This unit is covered by a -year guarantee from the date of supply, subject to correct usage. Within this period, the returned unit will be repaired in the factory or replaced free of charge. Unauthorised utilisation or incorrect connection will invalidate the manufacturer s guarantee. No liability will be assumed for any damage arising from such situations. 8 Technical specifications Heaters without fan Model No Dimensions in mm W H D Hole distance A mm Rated operating voltage V AC, 50/60 Hz, V DC Continuous thermal output W at T u = 0 C Ambient temperature -33 C +65 C Pre-fuse T 2 A 4 A Protection category IP 20 Protection class II We reserve the right to make technical modifications Heaters with fan Model No Dimensions in mm W H D Hole distance A mm 7 Hole distance B mm 53 (fitted rotated through 80 ) Rated operating voltage 230 V, 50/60 Hz 5 V, 50/60 Hz Continuous thermal output W at T u = 0 C 250/ /45 800/ / /400 70/800 Ambient temperature -33 C +65 C Pre-fuse gg f 4 A 6 A 6 A 4 A 6 A 0 A Protection category IP 20 Protection class II We reserve the right to make technical modifications. 6 Rittal enclosure heater assembly instructions
